Title: Non-aqueous electrolyte secondary battery
Inventor: KIDAI MASAYUKI
IPC: H01M10/05
Filed: 1996-10-15
Abstract: PROBLEM TO BE SOLVED: To enhance the safety by forming a solvent for non-aqueous electrolyte from fluoro-carbonate and chain carbonate as major components, and arranging so that their proportion by volume lies within the specific range. SOLUTION: A solvent for a non-aqueous electrolyte is prepared by mixing fluoro-carbonate with chain carbonate in a specific mix proportion by volume. The fluoro-carbonate should have such a structure that part or all of the hydrogen atoms of a chain or cyclic carbonate having carbonate group (-OCOO-) are substituted with fluorine atoms. For example, the chain fluoro-carbonate should have such a structure as expressed by the given equation, where R1 and R2 are alkyl group, provided that at least either of them is alkyl group in which part or all of the hydrogen atoms are substituted with fluorine atoms. The mix proportion by volume (fluoro-carbonate vs. chain carbonate) should range from 5:95 to 90:10. This allows enhancement of the safety against a destructive test for the battery.

Title: Method for high pressure drawing
Inventor: KAIDA NOBUYUKI
IPC: B21C9/00
Filed: 1987-10-28
Abstract: PURPOSE:To prevent oil from spouting at completion of drawing and seizing and breakdown after pressure reduction by bringing an inner surface restricting tool not to give a tube stock an external force in the opposite direction against drawing after reducing a pressure of lubricating oil in the end of drawing for a high pressure drawing of one type of forced lubricated tube manufacturing methods. CONSTITUTION:A high pressure container 1 accommodating a tube stock P is filled with high pressure lubricating oil and the stock P is drawn out through a gap between a die 5 and an inner surface restricting tool 3 from the container 1. After the rear end of the stock P in the drawing direction passes through a tube end detector 7, drawing of the stock P is paused and a pressure of the lubricating oil is reduced to the atmospheric pressure. After that, both a mandrel 2 and a seal cylinder 4 are retracted backward in the drawing direction. Hence, lubricating oil in the container 1 is discharge without spouting and finally the remaining part of the stock P is pulled out. In that stage, seizing, etc., are not generated because restriction by the tool 3 does not exist.

Title: Designing method of synchronous digital electronic circuit
Inventor: WERF ALBERT VAN DER
IPC: H04N5/91
Filed: 1993-10-29
Abstract: PURPOSE: To design the synchronous digital electronic circuit by adding delay, sending a signal to a subpath whose integral value exceeds a specific value and stopping integration, and holding minimum FFs for a basic cell and cell interconnection. CONSTITUTION: An integrating process advances sequentially to the right. For example, the integration result exceeds a clock pulse period behind a cell 74. At this point, a signal for inserting an FF into the subpath of an array of cells 50, 70, and 74 is outputted and the integration is stopped. In this process, integration is carried out until a number which is a little bit larger than the clock pulse period is obtained, which generates a good result, but is controlled, specially, when a predetermined integral value is reached, so that the integration is stopped. Similarly, when integration starts at another cell, 10 integration results are outputted. Some integration stops at the time of reaching the output terminal of a circuit, so all integration results need not exceed the specific clock pulse period.
